In the aftermath of the Sandy Hook Elementary School shooting, when NRA leader Wayne LaPierre made his infamous assertion that the “only way to stop a bad guy with a gun is a good guy with a gun,” he was tapping into the already well-seeded notion that hidden guns at arm’s reach of their private owners increase public safety.

It’s a powerful, seductive idea, particularly to Americans who favor personal liberty over communitarian ideals. It’s also completely wrong, according to a new analysis of nearly 40 years’ worth of crime data.

For every 830 individuals insured, the authors found, one life was saved. In medical terms, 830 in this context is the “number needed to treat.” To put this into perspective, the colonoscopy number needed to treat is 1250; you need to conduct 1250 colonoscopy screenings to prevent one colorectal cancer death.

Subjects under the influence of power, [Keltner] found in studies spanning two decades, acted as if they had suffered a traumatic brain injury—becoming more impulsive, less risk-aware, and, crucially, less adept at seeing things from other people’s point of view…

…And when [Obhi] put the heads of the powerful and the not-so-powerful under a transcranial-magnetic-stimulation machine, he found that power, in fact, impairs a specific neural process, “mirroring,” that may be a cornerstone of empathy. Which gives a neurological basis to what Keltner has termed the “power paradox”: Once we have power, we lose some of the capacities we needed to gain it in the first place.

The idea that an increasing sense of material precariousness can lead to cultural retreat from liberalizing “self-expression” values can help us understand why low-density white America turned out to support a populist leader with disturbingly illiberal tendencies. But this idea can also help us understand why our larger national culture seems to be growing apart in a way that has made it seem harder and harder to communicate constructively across the gap.

Okay, this one is a bit of a challenging read. It’s an interesting analysis, though, and from a libertarian rather than liberal source. And there’s fun with data visualization.

Contrary to the expert predictions (and ours), quitting was a wise decision for most. The alternatives were not so bad after all: People who worked in agriculture or market selling earned about as much money as they could have at the factory, often with fewer hours and better conditions. We were amazed: By the end of a year only a third of the people who had landed an industrial job were still employed in the industrial sector at all.

The return to experience is a way to describe what you get in return for aging. It describes the increase in wages that workers normally see throughout their careers….

…“This decline in the return to experience closely matches the decline in attachment to the labor force,” Case and Deaton wrote. “Our data are consistent with a model in which the decline in real wages led to a reduction in labor force participation, with cascading effects on marriage, health, and mortality from deaths of despair.”…

…If returns to experience are in decline, if wisdom no longer pays off, then that might help suggest why a group of mostly older people who are not, as a group, disadvantaged might become convinced that the country has taken a turn for the worse.
